| abstract |
Detergent additives for dry-cleaning solvents comprise a mixt. of at least one anionic and/or cationic surfactant (I) and a nonionic surfactant component (II) comprising at least in part, at least one alkyl polyglucoside (IIa). Pref. (II) comprises at least 50 (esp. 100) wt.% of (IIa), which is of formula R(G)n, where R = 10-14C alkyl, G = a glucose unit and n = 1.1-3, esp. 1.1-2. The compsns. contain 20-70 (esp. 35-60) wt.% of (IIa). ADVANTAGE - The compsns. have better cleaning performance (better soil removal, less grey discolouration), emulsifying power and filtration properties than compsns. contg. alkoxylated nonionic surfactants (cf. DE 2412175 and 3111158). |
